Zusammenfassung:Herein described is a supply device of at least two circuit branches (10, 20), each of said at least two circuit branches (10, 20) comprising at least one LED diode (30). The device comprises means (1) suitable for imposing the electric supply (Vout) of said at least two circuit branches (10, 20) and said means comprise at least one variable resistance (R2). The device comprises control means (3) coupled to said at least two circuit branches (10, 20) and suitable for varying said resistance (R2) in reply to a variation of the current (110, 120) that flows in one of said at least two circuit branches (10, 20) to vary the electric supply of said at least two circuit branches.
